Chainlink Beat Polymarket and Kalshi to the World Cup

ADI Predictstreet, FIFA World Cup 2026’s official prediction market partner, has adopted Chainlink as its exclusive oracle infrastructure. FIFA already lists ADI Predictstreet as the official prediction market partner for the tournament.

The partnership places Chainlink at the center of an estimated $2.37 billion in US prediction market trading volume projected for the tournament, and splits the market with Polymarket and Kalshi already drawing billions in World Cup bets.

The Problem Polymarket and Kalshi Couldn’t Solve

While both Polymarket and Kalshi hold federal CFTC approval, state-level regulators have moved aggressively against both platforms.

Officials in at least 11 states have issued cease-and-desist orders targeting their sports event contracts.

Nevada secured a court ruling blocking both platforms from operating in the state. Massachusetts won a preliminary injunction against Kalshi.

Tennessee demanded that both platforms void open contracts and refund deposits. Arizona filed 20 criminal counts against Kalshi for illegal gambling.

What Chainlink Actually Does Here

Chainlink provides the oracle layer, writing real-world FIFA match results onto the blockchain, then triggering automated market creation, settlement, and payouts through the Chainlink Runtime Environment (CRE).

This solves the manual resolution issue, which requires a human to confirm outcomes and settle positions, is slow and prone to disputes. By wiring official FIFA data directly into the settlement process, ADI Predictstreet removes that human bottleneck.

Dimitrios Psarrakis, CEO of ADI Predictstreet, pointed directly to this when explaining the choice. “Chainlink’s proven track record supporting large-scale markets made it a natural choice,” he said. “Through this integration, ADI Predictstreet can now provide transparent outcome resolution, efficient settlement, and fast payouts, establishing a new standard for how users engage with live sports prediction markets.”

A $2.37 Billion Moment for Chainlink

US prediction market volume alone is projected at $2.37 billion, according to research from Bookies.com. Kalshi is running 424 separate World Cup markets. Polymarket’s World Cup winner market crossed $1.9 billion in volume before the tournament even kicked off.

It remains to be seen what volume the official partner can bring in, but ADI Predictstreet’s official status puts it in a different category from other platforms for the duration of the tournament.

It uses FIFA’s data and branding, and a settlement layer that cannot be disputed after the final whistle.
